In this article:
Almost all dried vine fruit Produced in Australia is now delivered by growers to the Packing shed in open, half-tonne bins. The fruit may be stored under ambient conditions for many months before cleaning, processing and packing.
The uptake of moisture by the upper layers of fruit under these conditions may cause darkening and down grading of high Quality light Sultanas.
It also leads to difficulties in processing which result in skin damage, “sugaring”” and problems with stickiness and compaction.
